The end result of wisdom is... good deeds.
The Talmud in Wikipedia
For a thing to remain undone nothing more is needed than to think of it done
(January 08, 1601 - December 06, 1658)
If in our daily life we can smile, if we can be peaceful and happy, not only we, but everyone will profit from it. This is the most basic kind of peace work.
Thich Nhat Hanh
If your happiness depends on what somebody else does, I guess you do have a problem.
